Thanks for doing all that!
I know it might seem like I'm spending too much time to figure out a single song, but I
this PV so much. Perhaps my tenacity in this matter can be blamed on my university education, where we had to take apart ancient texts that were nowhere near as exciting!
I've already translated (well, more like interpreted) the video and uploaded it to Youtube. It can be seen here:
YouTube - ‪An Cafe - Natsu Koi ★ Natsu Game (subtitled) 【HD】‬‏ If you have any thoughts on how I interpreted the song, I'd be happy to hear them. One Japanese person already posted a comment about it.
How ingrained in Japan's cultural mindset is Cupid? Over here in America, he's just as well known as Santa Clause.
In a nutshell, Cupid is an angel that carries a bow and arrow, but he was originally a god from Greek mythology. His job was to make people fall in love by shooting poisoned arrows at their hearts. After being shot, whoever that person sees first they'll fall in love with. "Love at first sight," and this is mentioned near the beginning of the song. Cupid can turn himself invisible.
One of the things I mentioned was that at 1:24 it looks like the pianist got hit by something. The way he acts when hit and how he just runs along all happy after is just the way we picture it when people get hit by Cupid's arrow. What did you make of it?
Here you can see a comical representation of Cupid:

Is this not known about in Japan?
